3 下载OpenCV

官网链接🔗（选择 sources）

4 编译安装

unzip opencv-4.6.0.zip
cd opencv-4.6.0/
mkdir build
cd build/

#cmake

cmake -DCMAKE_BUILD_TYPE=Release -D OPENCV_GENERATE_PKGCONFIG=ON -DBUILD_EXAMPLES=ON -D CMAKE_INSTALL_PREFIX=/usr/local ..
cmake -D BUILD_TIFF=ON .. # 这句很重要解决上面问题的关键

#make
make -j8
sudo make install

#查看版本
opencv_version  # 4.6.0
pkg-config --modversion opencv4  # 4.6.0

5 后续过程

apt-get install pkg-config
 
vim /etc/ld.so.conf.d/opencv.conf   # (打开后加入/usr/local/lib，然后保存退出)
sudo ldconfig
 
sudo apt-get install vim-gtk
sudo vim /etc/bash.bashrc    # (加入PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig　\　export PKG_CONFIG_PATH  )
source /etc/bash.bashrc
	
find ./ -name opencv4.pc
# ./unix-install/opencv4.pc
 
pkg-config --cflags opencv4
# -I/usr/local/include/opencv4

6 验证

cd opencv/samples/cpp/
g++ edge.cpp -std=c++11 `pkg-config --cflags --libs opencv4`
./a.out
